FIG. 17 is an explodedperspective view of the coin slide, indicating the simplicity of assembly and sub stitution of parts. a

The coin slide of the invention is of the sliding plate type, wherein a recess or well of the slide plate carries a coin through a series of tests and accepts the coin or rejects it, depending upon ability of the coin to pass the tests. A proper coin will permit movement of the slide plate to a fully advanced position, at which position said plate may strike an actuating element of a vending machine, to initiate dispensing of an article or a service. The nature of the vending machine is of no consequence to the present invention, and such machine accordingly is omitted from th e accompanying drawings.

The apparatus comprisesin general, FIG. 1'7, a mount} ing bracket 20 inclnding a face plate 22 a base section 24 detachable from the bracket, a slide plate reciprocable upon the base section, and a latch plate 28 for, retaining the parts 2 4 and 26 inoperative relationship upon the mounting bracket. Byre sorting to a simple unhooking of the latch platens, the several parts 20, 24 and 26 may be quickly and easily disassociated one from another, as FIG. 17, for etfect ing replacement or. substitution of partsfor for making minor repair or adjustments with ease and dispatch. In this connection, it is' to be noted that the disassembly referred to is accomplished without removing the mounting bracket or the face plate from the wall of a cabinet which usually suppoi ts it. i

The slide plate 26 may be substantially flat, and will haveatinger piece or handle 30 atone end whereby the slide plate may be manually reciprocated. The opposite end 32 mayperform to initiate a dispensing operation,

when fully extended; Intermediate the ends 30 and 32, the slide plate may be provided with a well or. aperture 34 adapted to receive a coin 'or token, C placedtherein while the slide plate is fully retracted (FIG[ 1). The

coin or token is to be advanced past the face plate 22 and into the coin testing mechanism, by advancement of the slide plate by means of handle 30 to the right in FIG. 1.

With further reference to FIG. 17, base section 24 is seen to include a forwardly extending integral neck 36, Whose upper surface is grooved to provide. ribs38 upon which may'glide the slide plate 2 6 and any coin placed in well 34. 'About midway between the ends of base section 24, the middle ribs 38 terminate in inclines 40 sloping downwardly to a lower level provided by a stationary floor plate 42 upon which are formed spaced ribs 44 to support a coin descending from the level of ribs 38. Floor plate 42 is fixed relative to base section 24, and

terminates in an edge 46 beyond which an advanced coin is projected to drop into a suitable coin collecting compartment below, not shown. The upper wall or platform 48 of the base section beyond plate 42 is coplanar with ribs 38 and serves to support the slide plate 26.

It may here be noted that face plate 22 is apertured cross its width, as at 50, to receive the neck portion 36 of the base section, so that the free end of the neck may be inserted into bracket 20 to the extent that the free end of the neck abuts a stop 52 at the forward end of the bracket. In the inserted position aforesaid, lateral wings 54 of the base section rest within aperture 50 and are flush with the inner surface 56 of the face plate. Opposite sides of the mounting bracket 20 are grooved at 58 to embrace the side edges of neck 36, to prevent tilting of the base section relative to the mounting bracket. The base section is detachably secured in position upon the mounting bracket by means to be described.

Prior to insertion of base section neck 36 into aperture 50, the slide plate .26 is to be placed fiatwise atop the base section, over the ribs 38 and the platform 48, with the elongated ratchet slot 60 astride the fixed upadvancement thereof.

standing ears 62 carried by the base section. This places the handle 30 near the free end of neck 36, so that the base section with the slide plate overlying it may be inserted as a unit through aperture 50, this being accomplished by tilting the unit to thread the handle 30 and the neck 36 through the aperture. The height of aperture 50 is, of course, gauged to so accept the slide plate assembled upon the base section.

After the assembled slide plate and base section unit is applied to the mounting bracket, with neck 36 embraced by guides 58, the unit is latched against longitudinal dislocation by application of latch plate 28. The latch plate may be in the form of an elongate metallic strip as shown, having at its forward end a pair of extending fingers 64 to enter a pair of sockets 66 in the rear face of the face plate to prevent up-ending of the latch plate at its forward end. Displacement of the latch plate away from the face 56 of the face plate may be avoided by providing the latch plate with an aperture 68 to be hooked over an upright stationary post 70 fixed upon the face plate.

The rear end 72 of the latch plate may be held down on the slide plate 26 by passing a pin 76 through the 'apertured ears 62 of the base section, with the pin overlying the groove 74 in the end portion of the latch plate. This is best illustrated by FIGS. 1 and 13, wherein the pin is indicated at 76 passing through the ears 62. By merely removing the pin 76, latch plate 28 may be lifted off the post 70 to release the parts 26 and 24 for bodily displacement from the mounting bracket, as suggested by FIG. 17.

Pin 76 serves also to pivotally support a ratchet pawl 78 which is projected downwardly through slot 60 by means of a light spring 80, to engage the ratchet teeth 82 of the coin slide, for preventing improper slide manipulation back and forth after release of the slide following acceptance of a proper coin. This prevents cheating the vending machine by repeated actuation of the slide on one coin deposit.

If desired, the pin 76 may be temporarily fixed against accidental displacement from the ears 62, by bending against the head of the pin a thin lug 84 provided on the rear end of the latch plate (FIG. '1). The character 86 indicates a permanent magnet fixed tov the latch plate, for intercepting ferrous metal slugs deposited in the slide plate in an effort to cheat the dispensing machine.

The character 88 indicates an interceptor for slugs in the form of washers, and includes a depending finger 90 projectable by means of spring 92 to enter the hole of a washer slug advanced by the slide plate, and thereby stop Interceptor 88 may be pivoted as at 94 upon a side of the latch plate 28, FIG. 7. The finger 9t) bears yieldingly atop any coin or slug advanced by the slide plate, and when no coin or slug is present, the finger falls into the coin slide well 34 and thereby performs to limit advancement of the slide plate.

A coin-calipering means is provided, for effecting the rejection of coins or slugs of improper thickness or diameter, and for precluding full slide plate advancement on that account. The coin-calipering means is assembled wholly within the base section 24, and may therefore be replaced by another by the simple expedient of base section substitutions if desired. Thus, a base section equipped with calipering means for one denomination of coin may be quickly and accurately replaced with a similar base section equipped'with calipering means for coins of another denomination, all as by means of .a tension spring 104 stretched between the arm end 106 and a stationary post 106 fixed upon floor plate 42. Arm end 98 may be limited in its outward movement, by contact with the base section at 108, FIG. 2. Under certain conditions about to be explained, arm end )8 may sweep toward the major axis of base section 24, in a plane parallel to the mean plane of the base section.

Referring to FIGS. 5, 6 and 11, a stationary caliper shoe is indicated at 110 mounted upon the base section 24. The shoe includes a V-groove 112 in which may slide the edge of a coin advanced by slide plate 26. As will be understood, a thin coin will enter groove 112 somewhat farther than will a thicker coin.

Directly opposite the stationary caliper shoe 110 is located a movable caliper shoe 114, having a pivotal mounting 116 upon the base section. Shoe 114 is movable in the plane of coin C, and has a V-groove 118 therein in which the coin C may slide while advanced by the slide plate 26.

Comparing FIGS. 5 and 6, it will be observed that the genuine or acceptable coin C of FIG. 5, passing between the shoes 110 and 114, moves shoe 114 a greater distance about its pivot 116 than does the undersize coin of FIG. 6. This same result prevails if the coins are of equal dian1- eter, but with the coin of FIG. 6 reduced in thickness.

Movements of shoe 114 are translated to caliper arm 96 through the agency of an extending lug 120 on the arm, located in the path of movement of shoe 114. In FIG. 5, shoe 114 has moved lug 120 to shift the caliper arm 96 toward the. major axis of base section 24, whereas in FIG. 6 the coin, being undersize, has failed to move the shoe 114 and arm 96. As will be explained, slide plate 26 will be latched against full advancement unless coin C is properly dimensioned as to diameter and thickness, to shift the sweep end 98 of the caliper arm a certain distance toward the major axis of the slide plate, or of the base section 24.

The aforesaid latching of slide plate 26 against full advancement is performed by a latch element 122 (FIG. 16), pivoted upon the base section at 124 so that the nose 126 of the latch element may move into engagement with an abutment edge 128 of slide plate 26. A spring 139 yieldingly urges the latch element always toward the slide plate, so that whenever the slide plate is advanced longitudinally to bring edge 128 into register with the nose 126 of the pivoted latch element, the nose will tend to assume thelatched position of FIG. 16, unless the latch element is restrained from so moving into the path of advancement of abutment 128. FIG. 15 shows the latch element so held in restraint by the end 98 of calipering arm 96, permitting slide plate 26 to advance to the left without interference from latch element 122. The character 97 indicates a stool on the caliper arm adapted to glide upon the underface of base section 24 to stabilize and preclude flexing of the arm.

With reference to FIGS. 14 and 15, the latch element 122 is seen to carry an extension 132 terminating in a crowned ledge or keeper 134 projecting in the same general direction as the nose end of the latch element. This ledge or keeper 134 is situated so that the sweep end 98 (FIG. 14) of the caliper arm may move laterally onto the crowned ledge, as in FIG. 15, to restrain upward movement of the latch element into the path of slide plate abutment 128. Accordingly, when the sweep end 98 of the caliper arm is moved onto ledge 134 as in FIGS. 15 and 5, the slide plate 26 is free to move longitudinally to the fully advanced position for initiating action of a dispenser controlled thereby.

From the foregoing it will be apparent that the coin C of FIG. 5, being a coin of proper diameter and thickness, will effect movement of the caliper arm to the position of FIGS. 5 and 15, at which the slide plate carrying the coin is permitted full advancement without interference from latch element 122. On the t r hand, if

the coin of FIG. 6 is improper as to diameter Qilhfik fifi f the sweep end 98 of the caliper arm will failto rest upon the crown of ledge 134, and will therefore fail to restrain the latch element, resulting in the condition of FIG. 16 at which the slide plate 26 is latched against full advancement.

strain the latch element from stopping the slide plate.

As in most coin. slidedevices of -the general character herein disclosed, the coin-respective slide plate 26 carries a pair of depending coin pushers 136 and 138 (FIGS. 6 and 7), enforcing movement of the coin with the slide plate in two directions and on both levels38 and 44 of the base section illustrated by FIG. 17.

Withfurther referenceto the caliper means and latch element 122, attention. is directedto the. factthat no amount of abusive treatment directed to the slide plate can result in transfer of destructive impactto the calipering means, because the full force of any such impact is absorbed directly by latch element 122..while said latch element is out of contact with the. caliper arm. The

latch element. preferably is formed of a very tough and durable material, forexample nylon or some other dense plastic material of a suitable character. The base section 24 upon which the latch element is pivotally mounted is, of course, a most rugged constituent of the apparatus and will withstand excessive impact and strain imparted thereto by the latch element.

Directing attention to FIGS. 2, 9 and 10, the character 140 indicates generally a coin ejector the function of which is to project. a tested and accepted coin with some degree of force, downwardly and out of the path of coin advancement once it has reached therterminal edge 46 of floor plate 42. The ejector plays a part in preventing cheating the vending machine by reason of an accepted coin hanging in the slide plate aperture 34 and making possible'a limited slight reciprocation of the slide plate toobtain repeated vending action on a single coin.

The ejector may be in the form of a bell-crank shape fashioned from strip metal, and having arms 1'42 and 144*meeting at an angle, the area of meeting being perforated I0 receive a mounting stud.146. upon which the ejector may rock. Anangularly turned 'lug 148 of arm 142 projects into anopening 150 of floor plate 42, to prevent rotation of the ejector aboutstud 146,

Arm 144 of the ejector is bentupwardly in. substantiallyparallelism with lug .148, to provide a finger 154) adapted to bear yieldingly against the undertace of base section 24 in position to be struck and displacedby an advancing coin, see FIGS. 12 and 11. The finger 154) is normally kept elevated in the path of the advancing coin, by a spring 152 which encircles stud ldfiand bears against the pivot area of the ejector arms.

As a coin is advanced by the slide plate, its leading edge strikes the finger 15d, and displaces it downwardly from the path of coin advancement. Thereafter, the finger rides upon one face of the coin, the spring 152 pressing the finger against the coin face, FIG. 9, until finally the trailing edge of the advancing coin leaves the finger according to FIG. 10, causing the force of spring 15-2 to flip the coin and dislodge it from its position upon floor plate 42. Immediately upon dropping of the coin,

spring152 returns finger 150 to the initial position of FIG. 12 in readiness for acting upon a subsequently advancing coin. It maybe noted that finger 159 projects through an open slot 154 formed in the terminal edge 46 of floor plate 42.

The device of the invention is highly effective for distinguishing acceptable coins or tokens from those which are unacceptable, and in practice is found to prevent practically every known form of manipulation aimed at cheating or obtaining free play of a vending machine. The construction whereby movable parts are protected against damage from abusive treatment of the coinslide is especially meritorious, both from the standpoint of expense of maintenance, and reliability of continuous service. Noteworthy also is the disclosed method of assembly whereby substitution or replacement of constituent parts is greatly expedited and simplified, with substantial savings of time and skilled labor.

In conclusion,it should be noted that the caliper shoes indicated at are subject to easy replacement with shoes of different sizes, thereby to adapt the coin slide quickly and inexpensively for the accommodation of coins of dilierent denominations; or, if preferred, the entire base section of FIG. 17 may be quickly and easily removed for substitution with one embracingcaliper shoe gauged to the coin denomination desired. The slide plate '26 likewise is easily replaced with one having a coin-aperture of the required size.

It is to be understood thatvarious modifications and changes may be made in the structural details ofthe de= vice, within the scope of the appended claims, with-out departing from the spirit of the invention.
